what the difference for the two satellites:

DIRECTV-14, built by SSL (Space Systems/Loral) for operator DIRECTV to provide direct-to-home television broadcasts across the US
vs

GSAT-16

do they operate on the same bands. is one superior in technology to the other. i want to know how far we are in such technology capability

GSLV-Mark III countdown begins, launch tomorrow - Northern Voices Online | Northern Voices Online

This is going to be another great achievement for India on space front. To be true if it succeeds this launch and its effects will make all previous achievements look very small, unimportant. This will include even the launch of very successful Mangalyaan or Mars Orbiter that India successfully put in the Martian orbit merely this past October.

This morning the countdown for the launch of India's biggest and obviously heaviest rocket will begin at sharp 9Am. Geosynchronous Satellite Launch Vehicle (GSLV-Mark III) is making all the more headlines due to the fact that this massive rocket will also be taking a cockpit (obviously without humans or animals onboard) on its test flight.

GSLV-Mark IIIThe whole experiment will be taking as little as 20 minutes. Nonetheless it will be first step towards establishing the fact that Indian space scientists were well equipped to bring back rocket with capsule back on the earth from space. It is needless to say that Indian scientists are both excited and apprehensive prior to its launch. According to a tweet by the Indian Space Research Organisation (ISRO), the 630-tonne rocket will be powered by liquid and solid fuel engines while the cryogenic stage/engine will be a passive one. "The main purpose of the mission is to test the atmospheric characteristics and stability of the rocket on its way up. We also decided to use this opportunity to test one component of the crew module – a human space mission that India may embark on at a later date," M.Y.S Prasad, director of the Satish Dhawan Space Centre in Sriharikota, told reporters in a recent interaction.

Despite the fact that the launch is nothing more than an experimental mission, there is great excitement about it. Reports suggest that it will cost Rs.155 crore and will not carry any satellite as the cryogenic engine needed for the purpose is still under development, he said. "The cryogenic engine is under development and will take more two years to be ready," he said. As the other rocket engines are ready, ISRO decided to go ahead with this mission. "This will be India's new launch vehicle. It is bigger and can carry satellites up to four tonnes," said GSLV Mark III project director S. Somanath. As for the crew module, it will not carry any living being and is only for study purposes.

It is needless to say that the presence of a crew module is far more exiting for the world than the rocket itself. The main objective of the crew module is to demonstrate its re-entry flight and aero braking, and end-to-end parachute system validation. The rocket will go up to 126 km and the crew capsule will then detach and fall into the Bay of Bengal, 20 minutes after blast-off. The descent speed of the crew module will be controlled on board motors for some distance and then by three parachutes. The module will splash down 600 km from Port Blair and 1,600 km from the space centre. The capsule will be recovered by an Indian Coast Guard or Indian Navy ship. The crew module, looking like a giant-size cup cake – black on top and brown at the bottom – weighs around four tonnes. According to an ISRO official, it will be in the size of a small bedroom and can accommodate 2-3 people.

DRDO's PARACHUTE SYSTEM FOR RECOVERY OF MISSION CREW CAPSULE

The successful launch of GSLV MK3 by ISRO from Sriharikota on 18-12-2014, to validate Moon Mission Crew Capsule Recovery system equipped with Advanced parachute system designed and developed by ADRDE (Aerial Delivery R&D Estt), an Agra based lab of DRDO, proved the efficacy and reliability of the parachute system. The parachute deployment system functioned perfectly and achieved the required descent rate. ISRO has expressed happiness and thanked ADRDE & DRDO for the support.

The new launch vehicle designed by ISRO is capable to carry Crew Module (CM) weighing 4000 kg into the Space. The parachute system designed by ADRDE is to bring the module safely back to the earth after aero-braking phase from the hypersonic to subsonic speeds. Total 08 parachutes for various functions & redundancy were used in the recovery system for multi-stage deceleration of crew module speed to less than 11 m/s.

The final stage deceleration is achieved by two parachutes of 31 m diameter. This is one of the parachutes designed to be accommodated in limited space of crew module using high performance textiles, specially designed for this purpose. Before this launch, DRDO (ADRDE) had qualified the sub systems and the system through testing in 14 air drop tests from AN-32 Aircraft, IL-76 Aircraft and MI-17 Helicopter.

Through this trial DRDO (ADRDE) has proved the capability for safe recovery of crew module from space with payload of approximately 4000 kg. All parachute systems and sub-systems functioned as designed resulting into successful recovery in first effort depicting the text book performance.
ADRDE is the premier DRDO laboratory, one of its kind in the country, specializing in design development and leading to production para drop systems for a comprehensive range of military applications. A large number of such systems such as Combat Free Fall system, heavy drop systems, P 7 & P 16, capable of aerial delivery of payloads up to 7 tons and 16 tons respectively.

ISRO's unmanned crew module reaches Chennai

Three days after it was recovered from sea, ISRO's unmanned crew module was today brought to Kamarajar Port at Ennore near here on board a Coast Guard ship. Coast Guard ship ICGS Samudra Paheredar brought the three- tonne weighing crew module to the port and it was later shipped to Satish Dhawan Space Centre at Sriharikota, some 100 km from here, Coast Guard sources said. ISRO had earlier said that after being brought to Sriharikota, the module would be taken to Vikram Sarabhai Space Centre at Thiruvananthapuram in Kerala for further study. Inching towards realising India's ambition to send humans to space, ISRO had on December 18 successfully tested an unmanned crew module on board an experimental mission of its heaviest rocket GSLV Mark-III that blasted off from Sriharikota. Around 730 seconds after it lifted off at 9.30 AM from the Second Launch Pad of the Satish Dhawan Space Centre here, the crew module — CARE (Crew Module Atmospheric Re-entry Experiment) — splashed down into the Bay of Bengal, after separating from the LVM3-X rocket with active S200 and L110 propulsion stages. Few hours later, Indian Coast Guard ship recovered the module from the Bay of Bengal off Andaman and Nicobar Islands the same day and proceeded to Chennai.

Indigenous radar to be ready soon

The totally indigenous Rs. 240- crore multi-object tracking radar, which was developed and built by scientists of the Indian Space Research Organisation (ISRO) and some industries of the country, will be ready for operation during the first quarter of 2015. "The electronics, mechanical structure and radom of the radar are ready and integration of all components will start during the month-end. This is the first totally indigenous multi-object tracking radar," SHAR-ISRO Associate Director and Project Director of the radar V. Seshagiri Rao said here on Monday. "The new radar which will operate from Sriharikota range can track nearly 10 objects simultaneously in a distance as far as 1000 km in space, while the conventional radars spot a single object at a time. This is useful in many ways since it can detect 10 objects at a time and in case space debris is approaching an Indian satellite, the path of satellite can be diverted to avoid collision and damage," Mr. Seshagiri Rao explained about the radar while talking to The Hindu. "Antenna of a radar would move to track an object but in the case of the new multi-object tracking radar, its 12x6 meter antenna does not move but its electronic beam moves," he said about the radar.

ISRO chairman Radhakrishnan retires, MOM tweets farewell - Hindustan Times

I find it quite ridiculous and amusing in a sad way that the man who has given us so much success
is being allowed to go just like that .

Does he really wish to retire or is this some bureaucratic time line that he has crossed
and so some automatic procedures kick in and "has" to retire ?

surely we must further extend his tenure as he is probably in his fifties or maybe just hit 60
which is too young for retirement in this sort of non-physical work

I hope the higher ups in the indian govt will exercise discretion and keep a man who has achieved
so much in a relatively short span of time.

ISRO gears up to launch IRNSS 1D
After completing an eventful year, ISRO is gearing up for some satellite launches this year, with the IRNSS 1D being the first, which would put in place India's own navigation system on par with the Global Positioning System of the U.S.

IRNSS 1D is the fourth in the series of seven satellites, the national space agency is planning to launch to put in place the Indian Regional Navigation Satellite System (IRNSS).

While four satellites would be sufficient to start operations of the system, the remaining three satellites would make it more accurate and efficient.

HAL to open integrated cryogenic engine facility soon in Bengaluru

HAL after contributing to the success of Mars Orbiter Mission (MOM) and GSLV Mk III launch in 2014 is now taking steps to open Integrated Cryogenic Engine Manufacturing (ICEM) facility at Bengaluru.

"The facility is to be opened shortly at our Bangalore Complex and will focus on manufacture, integrate and test the Cryogenic Engine CE20 and Semi Cryogenic Engine SE2000 for launch of GSLV MKII and GSLV MKIII launch vehicles," said Dr R K Tyagi Chairman, HAL.

"When commissioned the facility will make HAL one among the technologically prudent companies across the globe," he added.

On R&D front, Dr Tyagi said HAL has done extremely well during 2014 by focusing on patents and Intellectual Property Rights (IPR). "Over the last three years, HAL has transformed itself into a technology company from being just a manufacturing company. The number of patents filed by HAL increased from 71 in 2012-13 to 209 in 2013-14 and to 773 in 2014-15," he said.

On projects front, HAL achieved major milestones in Light Combat Aircraft (LCA), Light Combat Helicopter (LCH), Light Utility Helicopter (LUH) and Su-30.

According to Dr Tyagi, the first series production of the LCA-Tejas took to the skies recently and is scheduled to be delivered to IAF soon. HAL designed and developed LCH Technology Demonstrator TD-3 made a maiden flight signifying a paradigm shift in the company's approach for design and development by building more prototypes to increase the number of flights needed for initial operational clearance (IOC) reducing the lead-time.

The Ground Test Vehicle (GTV) run of Light Utility Helicopter is yet another important milestone. The first ROH Su-30 aircraft was recently handed over to the Indian Air Force.

Talking about customer interface, Dr Tyagi said HAL senior executives visited various customer bases as part of confidence building measure to apprise its customers on the new initiatives undertaken by us.

HAL through new initiative dedicated for Integrity, Customer Focus and Quality (ICQ). "Here HAL was rated as 'Excellent' with a score of 1.08 for the year 2013-14 which is the best among all Defence Public Sector Undertakings (DPSUs). The company emerged in top six public sector companies out of over 180 PSEs assessed by Department of Public Enterprises (DPE)," claimed Dr Tyagi.

ISRO to put 7 Singapore and 1 Google satellite in orbit



While Singapore is helping Andhra Pradesh to build its capital, the Satish Dhawan Space Centre at Sriharikota is launching seven satellites for Singapore during its 50th Independence Day celebrations.

While Singapore is helping Andhra Pradesh to build its capital, the Satish Dhawan Space Centre at Sriharikota is launching seven satellites for Singapore during its 50th Independence Day celebrations. "This will build the emotional bond between Singapore and Andhra Pradesh. Singapore is keen on entering space research in a big way with the help of India," a senior Isro official said.

Meanwhile, the Isro is also launching three satellites for the UK-based DMC International Imaging International. DMCII is the company that manages the disaster monitoring constellation of the International Charter for Space and Major Disasters.

The PSLV-C28 would carry the three satellites weighing about 500 kg each by mid-2015. The ISRO is planning to launch the GSLV with GSAT-6 payload between July and August 2015.


Google Satellite ::
The Indian Space Research Organisation will also be launching a satellite for Google's Sky Box Imaging for GPS maps this year from its spaceport at Sriharikota.

This will be the first US satellite to be launched by Isro. Google, which has acquired the satellite imaging company Sky Box Imaging, wants to develop precision maps using its own network of 180-odd satellites.

The first among them is Sky Sat Gen II. Sky Box had entered into an agreement with Antrix Corporation before its takeover to launch the 120-kg satellite. It will be flown as a co-passenger along with the main payload during one of the satellite launchings this year. According to senior officials involved in space research, Google is keen on making use of Skybox satellites to keep Google Maps closer to real-time, accurate with up-to-date imagery.

Google is also keen on using Skybox's team and technology to help improve Internet access and disaster relief, the areas in which the company has long been interested.

Shar director Dr M.Y.S. Prasad said that Sky Box Imaging had approached them to launch one of its satellites and had also informed that they had plans to place 180 micro satellites in orbit. "They may launch experimental satellites before going ahead. Although they want to us to launch a single satellite now, there is potential in future. This is the first US-based satellite being launched by Isro," Dr Prasad said.
